"Samsung's recent Android 4.1.2 upgrade for the Galaxy Note 10.1 adds power and flexibility to the company's unique offering of Android multiwindowing features. With this update, the Galaxy Note 10.1 can run up to 16 multiwindow-enabled Android apps at once, Windows/Mac-like, on a single screen. Apps endowed with Samsung's multiwindow technology are usable in three viewing modes: full screen, dual view, and cascade view." There are already some complaining this represents a dangerous fork of Android. I thinks it's a step in the right direction.

Overall an interesting feature. Though I think this one will stay in the realm of techies.

From my own experience, I've seen users change their desktop behaviour to match the iOS experience. That is to say, they never previously used virtual desktops, but now use them regularly since MacOS introduced the Full Screen view for desktop apps. That's clearly the polar opposite of this development.

Still the more variations the better. I do believe forking represents a short term problem for Android but in the long run it's not a bad thing. Google releases will incorporate the best features in all the variants. The OEMS are basically providing Google with a nice test bed for new ideas.
